[IPython-dev] Fwd: Multi-line history problems in ipython (mac osx)

I recall that there was a bug filed in October regarding tab- 
completion / rlcompleter (Boyd filed it).   The thing is, the multi- 
line history problem doesn't occur in the stock python 2.5.1on  
Leopard.  It works fine.   But it doesn't work in iPython.  I also  
don't fully understand readline or editline, so I don't know (and  
haven't found the time to discover) where the problem originates.

I can/will log a bug, but I'd like to figure out the specifics -- I  
don't think that 'multi-line history in iPython borked' would get the  
right attention.  If anyone has anymore insight as to _why_ this  
occurs, please let me know.

Meanwhile I think I'll try to compile readline for my system -- it's  
better software (than libedit) anyway.
